What is teh mobile phase used in headspace gc when analyzing biodeisel
Accepted Answer
In headspace GC analysis of biodiesel, the mobile phase is typically an inert gas such as helium or nitrogen. These gases are chosen because they do not react with the sample components and have a low affinity for the stationary phase, which is usually a polar or non-polar capillary column. The mobile phase serves to carry the sample components through the column, separating them based on their interactions with the stationary phase.
